iPhone 5S and 5C? Apple Event Scheduled for Sept. 10

Those who have been waiting for the new iPhone will be happy to know we have a confirmed date. Well, not of the release date of that next phone but of Apple's event.

On Sept. 10, Apple will hold an event at its campus in Cupertino, Calif., the company confirmed in an invitation sent to members of the media this morning.

The invitation reads "This should brighten everyone's day." Surrounding the text are colorful dots, which match Apple's forthcoming colorful iOS 7 operating system and perhaps the colorful versions of the rumored iPhone 5C.

Apple will hold an event on Sept. 10 in San Francisco

The iPhone 5S and iPhone 5C are expected to be announced

The phones and the iOS 7 software are likely to be released the following week

Apple has been silent on the next version or versions of its popular smart phone, but the rumors have been very loud. According to many leaked photos, Apple will announce two phones -- the iPhone 5S, an update to the iPhone 5; and the iPhone 5C, a lower-cost phone.

The iPhone 5S has been said to have a similar design to the iPhone 5, but with a new fingerprint sensor embedded near the circular home button. The feature would add to the security of the phone. In addition, the iPhone 5S reportedly has a faster processor, improved camera and will be available in a new champagne or goldish color.

Joining the iPhone 5S is said to be a lower-cost phone called the iPhone 5C. According to various leaked images the 5C will come in a selection of colors (blue, green, white, yellow) and will be made of plastic. Apple experts speculate that the 5C will replace some of the more affordable iPhones, including the iPhone 4 or 4S. Neither of the new phones are expected to have larger screens than the 4-inch screen on the iPhone 5.

While the hardware details are unconfirmed, Apple has detailed the software. The next version of iOS -- iOS 7 -- looks radically different than previous versions with a new design and new features, including a Control Center with easy access to settings from any screen and new multitasking features.

Apple has released a new version of iOS in conjunction with new iPhones in years past. iOS 7 will be available for the iPhone 4, 4S and 5. It will also be out for the iPad 2, iPad with Retina and the iPad Mini.

ABC News will be at the event, which will be held at the company's Town Hall building at its campus and begins at 10 a.m. PT. Stay tuned for all our live coverage on Sept. 10.
